EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 766,575, dated August2, 1904.

Application filed November 19, 1903. Serial No. 181,806. No model.)

Beitknown that I, Lao F. ADT, of Troy. in the county of Rensselaer andState of New York, have invented certain new and useful Improvements inEyeglasses; and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to thereference-numerals marked thereon.

My present invention relates to improvements in eyeglasses; and it hasfor its object to provide improved nose-guards for a device of thischaracter having relatively fixed noseengaging portions adapted to restupon the sides of the wearers nose to insure a firm and proper seatingof the glasses thereon and adjustable portions movable relatively to thestationary portions and cooperating therewith to engage the nose toretain the glasses in position thereon with a minimum of pressure,suitable operating devices being provided by means of which theadjustable members may be readily released when it is desirable toremove the device from the nose.

To these and other ends my invention consists in certain features ofnovelty and advantage to be hereinafter more fully explained, andpointed out more particularly in the claims hereunto annexed.

In the drawings, Figure 1 is a perspective view of an eyeglass embodyingmy invention. Fig. 2 is a plan view thereof, partly in section. Fig. 3is a view showing the nose-engaging portions in side elevation. Fig. 4is a plan View showing another embodiment of my invention, and Fig. 5 isan end elevation of the same, showing one of the lenses removed.

In the views similar parts are designated by the same numerals ofreference.

An eyeglass constructed in accordance with that form of my inventionillustrated in Figs. 1 to 3, inclusive, embodies an arched bridge 1,preferably relatively inelastic and adapted, if desired, to rest uponthe crest of the wearers nose, the extremities of this bridge extendingoutwardly and thence doubling back to form the attaching ends 2 2, thatextend through the apertured lugs 3 3 of the lensclips 4 4. and receivefastening-screws 5 5, passing through the lenses and entering the clipsto secure said bridge rigidly in position. The free ends of the bridgeare thence extended downwardly, curved rearwardly, and finally doubledupwardly, forming the resilient loops 6 6, the extremities of the freearms of the loops terminating in the projections 7 T, the purpose ofwhich will presently appear. The material forming the loops in theembodiment shown in Figs. 1 to 3 is integral with the bridge, and, ifdesirable, that portion thereof composing the loops may be reduced incomparative cross-section or otherwise formed or treated to render itpliable and to secure the requisite elasticity. Over the arms of eachloop is fitted an adjustable nose-clamp having a nose-engaging portion 8at one end and the operating projection 9 at the opposite end thereof,and intermediate between these portions is provided a bearing formed bythe oppositely-disposed laterallyextending fingers 1O 11, locatedapproximately centrally of the clamp and preferably so curved as toembrace the arms of the loop, and between these fingers are sprung theresilient arms of the loop in such amanner that the projection 7 at theextremity of the rear loop-arm will enter an aperture in the adjacentfinger 11 to retain the clamp in its proper position.

In fitting the glasses to the nose of each particular person theoptician may readily bend the loops 6 6 into the proper curvature toproperly bear upon the sides of the nose, and in order to give theadjustable nose-clamps the proper set in relation to the lower portionof the guard formed by the loops the arms of the latter may be bent, bymeans of pliers or other suitable instrument, in such a manner that theproper set will be given the adjustable portions, and as the elasticityof the looparms produces a force tending to proximate these adjustableportions the amount of this force may also be varied in the same mannerto regulate the pressure of these nose-engaging portions on the wearersnose.

In Figs. 4: and 5 is illustrated another form of eyeglass embodying myinvention, wherein the bridge and nose-engaging portions are formedseparately and attached to the lenses and cheapening the process ofmanufacture and permitting bridges of different shapes or 3 dimensionsto be substituted and old guards to be replaced by new ones withoutrendering it necessary to discard the remainder of the mounting. In thisembodiment of my invention the ends of the bridge and the guards areproperly formed for attachment to the lens connections, and it will beunderstood that, if desired, a single screw-lens clip may be employedfor attaching the bridge and guards to the lenses instead of the stud orpost 12' An eyeglass embodying my invention may be readily andaccurately fitted to the nose of the wearer, as the relatively immovableor stationary guards or nose-engaging portions formed by the loops 6 6are so shaped and ar. ranged as to bear upon each side of the nose toinsure a firm and proper seating of the glasses, and by employing therelatively movable nose-clamping portions at the upper portion of theguards to engage the nose in proximity to the inner corners of the eyesunder the stress of the elastic arms of their respective loops it willbe obvious that the holding power of the nose-guards will effectuallymaintain the glasses in position without unduly pinching the skin of thenose. These movable nose-clamps may be readily adjusted by manipulatingthe handles or projections 9 9 by the thumb and forefinger of thewearers hand pressing them together, causing the nose-engaging portions8 8 to separate and release their grasp upon the nose to permit theglasses to be removed, and when they are released they will moveinwardly under the torsional action of the elastic loops 6 6, causingthem to clamp the nose when the glasses are in position thereon. Thesemovable nose-clamps may be readily removed when desired by pressing thearms of the loops together to such an extent as to disengage said armsfrom their corresponding fingers l0 and 11, thereby enabling thelooparms to be freely bent into any desired position by the Opticianwhile fitting the glasses.

In an eyeglass ofthis character it is advantageous to employ a rigid orrelatively inelastic bridge, as such a construction will enable thepupillary distance and other important relations between the lenses tobe accurately preserved and maintained irrespective of the variousadjustments of the glasses upon the wearers nose; but it will beunderstood that various forms of bridges may be employed to meet theexigencies of various conditions.

I claim as my invention 1. In eyeglasses, the combination with thelenses and a bridge connecting them, of a noseguard for each lens havinga relatively immovable lower portion. adapted to rest against thewearers nose, and a nose clamp movably l mounted at the upper portion ofthe guard and having operating projections forpermitting it to beadjusted to the nose. l 2.
